Signaling of beam correlation across millimeter wave frequency bands

Abstract

Methods, systems, and devices for wireless communications are described. A first wireless device may receive, from a second wireless device, a carrier aggregation configuration including two millimeter wave frequency bands for communications. The first wireless device may determine a beam correlation parameter based on the carrier aggregation configuration. The first wireless device may determine beams, based on the beam correlation parameter, in the two frequency bands. The first wireless device and the second wireless device may communicate in carrier aggregation using a beam on a first frequency band and a second beam on a second frequency band.

What is claimed is: 
     
         1 . An apparatus for wireless communications at a first wireless device, comprising:
 one or more memories; and   one or more processors coupled with the one or more memories and configured to cause the first wireless device to:
 receive, from a second wireless device, a carrier aggregation configuration for communications with the second wireless device, the carrier aggregation configuration comprising at least a first frequency band and a second frequency band; and 
 communicate, with the second wireless device, in carrier aggregation using a first beam on the first frequency band and a second beam on the second frequency band, the first beam and the second beam being based at least in part on a beam correlation parameter, the beam correlation parameter based at least in part on the received carrier aggregation configuration and indicating a correlation between the first beam and the second beam in a direction based at least in part on the carrier aggregation performed in the direction in the first frequency band and in the second frequency band.
